Title: Process for producing anhydrous magnesium chloride from magnesium chloride lyes or higher magnesium chloride hydrates
IPC: F02M23/03
Filed: 1939-01-04
Abstract: 512,390. Anhydrous magnesium chloride. MAGNESIUM ELEKTRON, Ltd. (I.G. Farbenindustrie Akt.-Ges.). Jan. 4, 1939, No. 318. [Class 1 (iii)] Anhydrous magnesium chloride is produced from magnesium chloride lyes or higher hydrates of the salt by dehydration of the fused higher hydrates by spray-drying, thereby converting them into lower hydrates, and then treating the'latter at a suitably high temperature with chlorine in the presence of carbon. Magnesium chloride hexa hydrate may be the material initially used in the process, or magnesium chloride lyes may themselves be subjected to the drying action of hot gases ; preferably, however, the lyes are first evaporated down to the hexa hydrate or to a lower hydrate, which is fused and sprayed with hot compressed air in concurrent flow with flame gases. The dried product, consisting largely of the monohydrate together with foreign salts and a small percentage of magnesia, is extremely porous, and when mixed with about 3 per cent. of carbon (brown coal dust) is moulded, without the use of a binding agent, into shaped pieces. These are treated on a permeable support, preferably electrically heated, with chlorine passed upwardly, anhydrous magnesium chloride thus formed running off through the support.

Patent GB-989803-A (GB)
Title: Improvements relating to organic semi-conductors
IPC: C08G79/025
Filed: 1962-01-10
Abstract: An organic semi-conductor consists basically of an emitter of ionizing radiation and a metallic salt Friedel-Craft catalyst dispersed in a copolymer of acrylonitrile and of one or more phosphonitriles substituted by halogen atoms or by hydroxy, alkoxy, aryloxy, amino, or substituted amino radicals.  In the case of semi-conductor material used for rectifiers molybdenum sulphide or a mixture of this with lead sulphide is included in the composition in proportions of up to 20% by weight of the copolymer. The weight ratio in the copolymer of acrylonitrile residues to phosphonitrile residues is made between 0.5: 1 and 5.5: 1, and the metallic salt is present at between 0.1% and 2% by weight of the copolymer.  The semiconductor is made by mixing solutions of the three components and by then evaporating the solvent or solvents.  Radiation sources used are a -emitters such as compounds of U238 or b -emitters such as compounds of promethium or tritium.  (Tritium is incorporated in compounds such as ethyl stearate or hydrocarbon oils.)  it is stated that g -emitters may sometimes be preferred. The preferred metallic salt Friedel-Craft catalyst and the only example given is zinc chloride. In an example a copolymer is prepared by dissolving phosphonitrilic chloride in excess acrylonitrile, adding benzoyl peroxide as a catalyst, and heating the mixture to about 75 DEG  C. in an atmosphere of nitrogen or carbon dioxide, the mixture being kept at this temperature until the reaction is completed.  The excess acrylonitrile is separated from the precipitated white copolymer by evaporation.  For making two examples of the semi-conductors the copolymer, which may contain polyacrylonitrile, polyphosphonitrile, and unpolymerized phosphonitrilic chloride as impurities, is dissolved by refluxing in dimethyl formamide.  To some of this solution a dimethyl formamide solution of uranyl nitrate is added followed by a dimethyl formamide solution of zinc chloride.  The semi-conductor is obtained by removal of the solvent, for example by casting the solution on to a planar surface and subjecting it to I.R. heating. The uranyl nitrate is present at a concentration of 2 parts by weight to 3 parts by weight of copolymer and the zinc chloride concentration is in the range 0.1 to 1% by weight of the copolymer. To make the second semi-conductor an aqueous solution of promethium chloride is added to some of the copolymer solution, a dimethyl formamide solution of zinc chloride added, and the solvents then evaporated.  Composite semi-conductor bodies may be built up by casting successive layers of the same semiconductor or by casting layers of the two semi-conductors alternately one upon the other. The Specification describes the use of the materials in the production of rectifiers and capacitors (see Division H1).

Title: A process for plating an article with a gold-based alloy
Inventor: IKEDA SHINJI
IPC: C23C14/14
Filed: 1987-11-05
Abstract: A dry ionic process for gold plating substrate articles 5 comprises suspending an article from a holder 2 in a vacuum chamber 1 above a heated bath of a gold-based plating alloy 3 and applying a voltage from an electrical supply 4 between the articles 5 and the bath 3 to deposit vapour of the alloy. The invention lies in the use in the bath of a gold- based alloy containing at least one of the following alloying metals:- chromium, iron, cobalt, nickel, palladium and copper, the content of the or each alloying metal being, for the chromium, iron, cobalt and nickel in the range of from 1% to 10% by weight, and for the palladium and copper in the range of from 0.5 to 20% by weight and the balance of the alloy except for impurities being gold, and heating the alloy in the bath to a temperature in the range of from 1000 DEG  to 1500 DEG C. By the use of an alloy as described above, the process can be carried out using a single alloy bath instead of using two or more different baths from which single metals are vaporized simultaneously and in this way various difficulties previously encountered are avoided. Despite the simplification of the process, the plating obtained is satisfactory in all respects including the control of the colour tone of the plated surface and the corrosion resistance and adhesion strength of the plating. <IMAGE>

Abstract: PURPOSE:To improve life characteristics by providing one part of the outer circumferential region of a fine solder group connecting a metallic layer carried to a semiconductor base body and a metallic layer carried to a dielectric substrate with a means controlling the shape of the fine solder group. CONSTITUTION:A metallic region 111 is brought into contact with a metallic layer 16a at a step when a chip 10 and a substrate 12 are positioned, but a fine solder 11 is not brought into contact with a metallic layer 16b. When flux is applied to an assembly and heated in a nitrogen atmosphere, the fine solder 11 begins to melt at approximately 183 deg.C, the metallic region 111 begins to melt at approximately 290 deg.C, and both the solder and the region are melted completely at a maximum temperature of 350 deg.C. When the chip 10 and the substrate 12 are pushed each other under the state, the fine solder 111 and the metallic layer 16b are joined. A clearance between the chip 10 and the substrate 12 is expanded by the surface tension of the metallic region 111 with the release of pushing, and the fine solder 11 is adjusted to a shape of a diameter smaller than metallic layers 15b and 16b. Accordingly, the form of a connecting section in a region to which thermal stress is applied is controlled, thus improving the life characteristics of a fine connecting package structure.

Abstract: PROBLEM TO BE SOLVED: To utilize, as a driving force, electrostatic attracting force and repulsion force in the X and Y directions generated between electrode arrays by supplying multi-phase voltage to the electrode arrays in the X, Y directions provided respectively to the electrode boards provided opposed with each other. SOLUTION: An electrostatic actuator has an electrode board of an upper rotor 1 and an electrode board of a lower stator 2 and relatively displaces these boards while these are placed in contact. The rotor electrode arrays 1a, 1b, 1c, 1d are respectively formed to the electrode board of the rotor 1, while the stator electrode arrays 2a, 2b, 2c, 2d are respectively formed to the electrode board of the stator 2. When 3-phase voltage is supplied to each electrode array of respective electrode board with a voltage supply circuit, since an electrostatic attracting force and repulsion force is generated in the X and Y directions between electrode arrays, such a force can be used as the driving force. Here, there is a merit that relative displacement in the other direction may be made only with one voltage supply circuit.
